There is no classical counterpart to tunneling, but a decrease in the tunneling in a short time interval may be interpreted as an approach of a quantum system to a classical system. We show that changing the square barrier by increasing the height/width do not only decrease the tunneling but also slows down the rapid rise of the entropy function, indicating that the entropy growth is an essentially quantum effect.", "revisions": [ { "version": "v1", "updated": "2015-07-17T06:11:51.000Z" } ], "analyses": { "keywords": [ "quantum chaos", "square barrier", "spatial entropy function", "short time interval", "wave function" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
